Parameters
- key
-
Type:
System::String^
A unique identifier for the cache entry.
- value
-
Type:
System::Object^
The object to insert.
- policy
-
Type:
System.Runtime.Caching::CacheItemPolicy^
An object that contains eviction details for the cache entry. This object provides more options for eviction than a simple absolute expiration.
- regionName
-
Type:
System::String^
Optional. A named region in the cache to which the cache entry can be added, if regions are implemented. The default value for the optional parameter is null.
This method overload lets you provide more eviction or expiration details than those that are available in time-based absolute expiration.
If an item that matches key does not exist in the cache, value and key are used to insert as a new cache entry. If an item with a key that matches item exists, the cache entry is updated or overwritten by using value.
